本欧洲标准规定了加速实验室方法，用于测量根据EN 1504-3 1）中定义的修理产品和系统对二氧化碳渗透的抵抗力。该方法适用于评估修补灌浆，砂浆和混凝土的性能，而不采用保护涂层系统。该方法不测量通过吸收其它酸性气体（例如SO 2，HCl等）可能发生的pH值降低的阻力

This European Standard specifies an accelerated laboratory method for measuring the resistance against carbon dioxide penetration through repair products and systems, as defined in EN 1504-3 1). The method is suitable for assessing the performance of repair grouts, mortars and concretes without a protective coating system applied. The method does not measure the resistance to reduction in pH-value that may occur by absorption of other acidic gases (e.g. SO2, HCl etc.).
